Hi, (...) The correct > formula should be: > > m: 2 ** 160 > q: 1 * (1 - (1 / m)) * (1 - (2 / m)) * ... * (1 - (n - 1 / m)) > p: 1 - q > > , where Q is the probability that no collision occurs.
(...) So the chance for a collision among n elements seems to be 1 - (m! / ((m-n)! * m^n)) -- Holger Kruse [EMAIL PROTECTED] If I use the formula correctly, the probability of a collision in a set of 1 M samples is somewhere around 2 ** -120. -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
